ATTACKS & VULNERABILITIES

TLDR InfoSec

FAKE CALENDLY INVITES SPOOF TOP BRANDS TO HIJACK AD MANAGER ACCOUNTS

There is an ongoing phishing campaign that uses Calendly to impersonate popular brands to phish for business ad manager accounts. These accounts are tempting for threat actors as they can be used as a springboard to launch malvertising campaigns with advanced features like geo-targeting, domain filtering, and device-specific targeting. The victims receive a Calendly invite from the threat actor impersonating a recruiter with a fake meeting invitation, which directs the user to an Attacker-in-the-Middle phishing page that attempts to steal login credentials.

HOW A RUSSIAN THREAT ACTOR USES A RECENT WINRAR VULNERABILITY IN THEIR UKRAINE OPERATIONS

Primitive Bear (Gamaredon), an FSB-attributed APT group, exploited CVE-2025-6218, a critical WinRAR path traversal vulnerability affecting versions through 7.11, in targeted spear-phishing campaigns against Ukrainian military units and government entities using military-themed lures. The attack chain leveraged malicious RAR archives containing HTA files with obfuscated VBScript, weaponizing a path traversal flaw to write payloads directly to Windows Startup folders, then used mshta.exe as a LOLBIN to fetch secondary-stage malware from a DynDNS-based C2 infrastructure across 14 active domains. The campaigns demonstrated sophisticated tradecraft, including minimal obfuscation, multi-stage payload delivery, phishing URL masquerading (president.gov.ua@malicious-domain), and infrastructure leveraging InterLIR IP marketplaces and No-IP dynamic DNS services. Defenders are recommended to update WinRAR to 7.12+, block HTA execution via AppLocker/WDAC, and monitor LOLBIN abuse and Startup folder modifications.

AWS SECRETS MANAGER ANNOUNCES MANAGED EXTERNAL SECRETS

Managed external secrets is a new capability in AWS Secrets Manager that allows automatic rotation for participating third-party SaaS secrets without the overhead of rotation, Lambda function creation, or management. At present, the supported third-party vendors are Salesforce, BigID, and Snowflake. AWS has released a guide for becoming an integrated third-party vendor. The guide demonstrates how to create, manage, and view external secrets.

AI AGENTS FIND $4.6M IN BLOCKCHAIN SMART CONTRACT EXPLOITS

SCONE-bench, created by Anthropic researchers, contains 405 exploit-prone smart contracts. Claude Opus 4.5, Sonnet 4.5, and GPT-5 exploited 34 contracts worth $4.6 million. Sonnet 4.5 and GPT-5 found two new zero-day vulnerabilities in 2,849 new contracts, producing exploits worth $3,694 at an API cost of $3,476 for GPT-5. This shows that profitable autonomous exploitation is feasible with current models. Security teams should adopt AI agents for smart contract auditing before deployment, as the decreasing window for exploitation and dropping costs ($1.22 per run) give attackers advantages, while enabling proactive vulnerability detection and fixing.

TELEGRAM'S COCOON NETWORK GOES LIVE, CHALLENGES AMAZON, MICROSOFT IN AI COMPUTE

Telegram Cocoon is a TON blockchain-based decentralized AI compute network that connects GPU providers (compensated in toncoin tokens) with privacy-focused applications that require AI model execution. It is positioned as a confidential alternative to centralized cloud providers like Amazon and Microsoft. The network employs attested compute layers to process AI requests while settling payments on-chain. Security professionals should note ecosystem concerns, including hardware limitations restricted to specific Intel processors, potential scrutiny of the "100% confidentiality" claims, and the strategic implications of a central messaging platform controlling AI compute infrastructure that could process sensitive organizational workloads.

GLASSWORM MALWARE RETURNS IN THIRD WAVE OF MALICIOUS VS CODE PACKAGES

Glassworm malware returned for a third wave on OpenVSX and Microsoft Visual Studio marketplaces with 24 new packages impersonating popular developer tools. The supply chain attack evolved to use Rust-based implants alongside invisible Unicode character obfuscation, steals GitHub, npm, and OpenVSX credentials plus cryptocurrency wallet data from 49 extensions, deploys SOCKS proxies for traffic routing, and installs HVNC clients for stealthy remote access while manipulating download counts to boost search rankings. Development teams should immediately audit installed VS Code extensions against published IOC lists, verify publisher authenticity before installation, monitor for suspicious extension updates, and implement controls to detect invisible Unicode characters in code reviews to prevent credential theft and environment compromise.

VULNERABILITY IN OPENAI CODING AGENT COULD FACILITATE ATTACKS ON DEVELOPERS

A command-injection vulnerability in OpenAI's Codex CLI allows trusted local configuration files to execute attacker-controlled commands without user approval. By slipping malicious configs into a repository, an attacker could gain remote access, run arbitrary commands, steal secrets, and even poison supply chains via CI and build systems. OpenAI fixed the issue in Codex CLI version 0.23.0 after disclosure.
